"Do not proceed" on filevaulted system after 10.7.2

I have a Macbook Air (mid-2011) system I use for preproduction testing. Previously, I had installed 10.7.1 and filevaulted the system. Today, after installing the 10.7.2 update via Software Update, the machine booted to the Do not proceed symbol (grey circle slash). As this is a MacBook Air, there's not a really easy way to target disk mode to another machine (this is my only Thunderbolt system). I determined I was able to boot to Verbose/Single user mode by holding the key combination prior to the encryption screen, which provided the following diagnostic output:

Still waiting for root device

Precisely as expected, based on my previous experience with PGP'd macs.

On PGP, I was able to mount disk0s3 from the another machine's Terminal app, delete boot.efi from the Boot OS X partition, and replace it with a renamed pgpboot.efi. Digging around in a similar fashion with Filevault, I was able to find a similar recovery partition at disk0s3, but no similar boot.efi files for replacement.

Anyone have any thoughts on recover here? No data loss for me on this system, but I just wanted to get this out there for anyone having similar issues.

Try restarting while holding command-R down to get to recovery-HD mode. Reload Lyon from there (requires internet connection for the download). It will ask for the FileVault unlock key to gain access to the to the disk before it will proceed.

Arghhhh.. Same exact issue here on a Macbook Pro (2011). FileVaulted filesystem. PGP installed (but drive not encrypted with PGP WDE, just with FileVault2). Updated to 10.7.2. Same boot issues. Attached is screenshot for verbose boot.... I get prompted to enter the FileVault password, but afterwards this happens...

in recovery terminal, I had to dig through the PGP.app to find an uninstall script. From that, I found all the rm statements. In /Applications, do the following find command to see the uninstall script - do not remove via "rm" any of the files yet - move then aside

find . -name uninstall* -print

./PGP.app/Contents/Resources/uninstall_pgp.pl

I moved them aside with the same directory structure that I found them in, in a directories like

.../PGP-uninstalled/Library/Receipts/...

Then, I rebooted, but still had no joy - stuck at a PGPWDE boot loader error.

Going line by line in the uninstall_pgp.pl script, I took these lines and did them by hand, pulling the required files from my moved aside files ... if they are deleted you are toast, cause I could not find them in the DMG. You could pull them from another machine's install if needed. The key to these lines are that it fixes the boot setup to not have PGP in the mix.

Christopher Graham5 (and anyone else with this problem) I did not have to go thru your extra steps but I did boot off a recovery jump drive I created with Lion instead of the recovery partition, don't know if that made a difference.

Okay - what you need to do is after you boot into the recovery mode, go to Disk Utility and dounble click on your drive. It will ask for a password, and then mount the drive. Exit Disk utiltity, then go to the Recovery Terminal via the menu item.

My password was not the alpha-numeric, but rather the master filevault password I set. You may just need to put in your user password, but I did not try that one.
